Yes. A very large number of people from engineers to laborers are now designing a very low cost, DIY rotary water well drilling rig that will mount on a low cost, DIY tractor.
Those and many other machines are in development and already have a license requiring the designs to be free for anyone to build or manufacture and sell from now on (oh...engineers, laborers, technicians and legal support to give the effort some sticking power, too). The change is coming and the enhanced security of distribution and localization of production with it (i.e., not so centralized).
Now, be the person, who has that capability- in such, an event. Now, be the person, who does not... see any problems?
